SiGe powder, kwaziwa njengei-silicon germanium powder, yinto efunyenwe ingqwalasela enkulu kwinkalo yeteknoloji ye-semiconductor.Eli nqaku lijolise ekuboniseni ukuba kutheniSiGeisetyenziswa ngokubanzi kwiinkqubo ezahlukeneyo kwaye iphonononge iipropati zayo ezizodwa kunye neenzuzo.
I-silicon ye-germanium powderyimathiriyeli ehlanganisiweyo eyenziwe ngesilicon kunye neeathom zegermanium.Ukudibaniswa kwezi zinto zimbini zenza izinto ezineempawu eziphawulekayo ezingafumanekiyo kwi-silicon ecocekileyo okanye i-germanium.Esinye sezizathu eziphambili zokusebenzisaSiGekukuhambelana kwayo okugqwesileyo kunye neetekhnoloji ezisekwe kwisilicon.
UkudibanisaSiGekwizixhobo ezisekelwe kwi-silicon zibonelela ngeenzuzo ezininzi.Enye yeenzuzo eziphambili kukukwazi ukutshintsha iimpawu zombane ze-silicon, ngaloo ndlela kuphuculwe ukusebenza kwamacandelo e-elektroniki.Xa kuthelekiswa nesilicon,SiGeineelektroni eziphezulu kunye nokuhamba komngxuma, okuvumela uthutho lwe-electron olukhawulezayo kunye nokwanda kwesantya sesixhobo.Le propati inenzuzo ngokukodwa kwizicelo ze-high-frequency, ezifana neenkqubo zonxibelelwano ezingenazintambo kunye neesekethe ezidibeneyo ezikhawulezayo.
Ukongeza,SiGeine-gap yebhendi esezantsi kune-silicon, eyivumela ukuba ifunxe kwaye ikhuphe ukukhanya ngokufanelekileyo.Le propati yenza ukuba ibe yinto ebalulekileyo kwizixhobo ze-optoelectronic ezifana ne-photodetectors kunye ne-light-emitting diodes (LEDs).SiGeikwanayo ne-thermal conductivity egqwesileyo, eyivumela ukuba ikhuphe ubushushu ngokufanelekileyo, iyenze ilungele izixhobo ezifuna ulawulo olusebenzayo lobushushu.
Esinye isizathu sokubaSiGeUkusetyenziswa ngokubanzi kukuhambelana kwayo neenkqubo ezikhoyo zokwenziwa kwesilicon.SiGe powderinokuxutywa ngokulula nesilicon kwaye emva koko ifakwe kwi-silicon substrate isebenzisa iindlela eziqhelekileyo zokwenziwa kwe-semiconductor ezifana ne-chemical vapor deposition (CVD) okanye i-molecular beam epitaxy (MBE).Oku kudityaniswa kwe-seamless kwenza kube yindleko kwaye iqinisekisa inguqu egudileyo kubavelisi asele beseke amaziko okuvelisa asekelwe kwi-silicon.
SiGe powderinokwenza kwakhona i-silicon edibeneyo.Uxinzelelo lwenziwa kumaleko wesilicon ngokufaka umaleko obhityileyo weSiGephezu kwe-silicon substrate kwaye ngokukhetha ngokususa iiathom zegermanium.Olu hlobo lutshintsha ulwakhiwo lwebhendi ye-silicon, iphucula ngakumbi iimpawu zayo zombane.I-silicon egxininisiweyo ibe yinto ephambili kwii-transistors eziphezulu zokusebenza, eyenza isantya sokutshintsha ngokukhawuleza kunye nokusetyenziswa kwamandla aphantsi.
Ukwengeza,SiGe powderinoluhlu olubanzi lokusetyenziswa kwintsimi yezixhobo ze-thermoelectric.Izixhobo zombane we-thermoelectric ziguqula ubushushu bube ngumbane kwaye ngokuphambeneyo, zibenza zibaluleke kakhulu kwizicelo ezifana nokuveliswa kwamandla kunye neenkqubo zokupholisa.SiGeine-conductivity ephezulu ye-thermal kunye neempawu zombane ezityhutyhulwayo, ezibonelela ngemathiriyeli efanelekileyo yokuphuhliswa kwezixhobo ezifanelekileyo ze-thermoelectric.
Ukuququmbela,SiGe powder or i-silicon germanium powderineenzuzo ezahlukeneyo kunye nokusetyenziswa kwinkalo yetekhnoloji ye-semiconductor.Ukuhambelana kwayo kunye neenkqubo ze-silicon ezikhoyo, iimpawu ezibalaseleyo zombane kunye ne-thermal conductivity yenza ukuba ibe yinto eyaziwayo.Nokuba kuphuculwe ukusebenza kweesekethe ezidibeneyo, ukuphuhlisa izixhobo ze-optoelectronic, okanye ukwenza izixhobo ezifanelekileyo ze-thermoelectric,SiGeiyaqhubeka nokungqina ixabiso layo njengesixhobo esinemisebenzi emininzi.Njengoko uphando kunye neteknoloji ziqhubeka ziqhubela phambili, silindeleSiGe powdersukudlala indima ebaluleke ngakumbi ekubumbeni ikamva lezixhobo ze-semiconductor.
